Socket and electronic device

Abstract

A socket (10) includes a first insulator (20), a second insulator (30), and contacts (50). The first insulator (20) is in the form of a frame. The second insulator (30) is movable relative to the first insulator (20). The contacts (50) each include a support portion supported by the first insulator (20) and are disposed within the second insulator (30). The contacts (50) each include an elastic portion (54) and a movable portion (55). The elastic portion (54) is linked to the support portion and is located between the support portion and the second insulator (30). The movable portion (55) includes a contacting portion (55c) for contact with a connection object (60). The movable portion (55) is farther than the elastic portion (54) from a periphery of the second insulator (30) and is movable relative to the second insulator (30).

The invention claimed is: 
     
       1. A socket, comprising:
 a first insulator in a form of a frame; 
 a second insulator that is disposed within the first insulator in a manner so as to be movable relative to the first insulator; and 
 contacts each including a support portion supported by the first insulator, the contacts being disposed within the second insulator, wherein 
 the contacts each include
 an elastic portion linked to the support portion and located between the support portion and the second insulator, 
 a movable portion that is farther than the elastic portion from a periphery of the second insulator and is movable relative to the second insulator, and 
 a contacting portion for contact with a connection object, 
 
 wherein the second insulator includes an accommodating portion protruding toward the first insulator in a direction orthogonal to a direction of fit between the connection object and the socket, the accommodating portion and the first insulator face each other in the direction of fit, and a tip of the elastic portion in the direction of fit is located within the accommodating portion in the direction of fit, 
 wherein the second insulator includes at least one protrusion protruding outward from the accommodating portion in a direction orthogonal to the direction of fit, and 
 wherein the at least one protrusion comprises a plurality of protrusions arranged along the accommodating portion, and the mounting portions of the contacts are each located between adjacent ones of the protrusions when viewed in plan in the direction of fit. 
 
     
     
       2. The socket according to  claim 1 , wherein the contacts each include at least one pullout-preventing portion protruding from a side surface of the movable portion toward an inner wall of the second insulator, and the second insulator includes pullout prevention target portions being part of the inner wall and facing tips of the pullout-preventing portions in a direction of fit between the connection object and the socket. 
     
     
       3. The socket according to  claim 2 , wherein the at least one pullout-preventing portion comprises a pair of pullout-preventing portions, and each pullout-preventing portion of the pair of pullout-preventing portions protrudes from a corresponding one of two opposite side surfaces of the movable portion toward the inner wall of the second insulator. 
     
     
       4. The socket according to  claim 1 , wherein the movable portion has a rectangular shape when viewed in a direction of fit between the connection object and the socket. 
     
     
       5. The socket according to  claim 1 , wherein the support portion and the elastic portion extend flatly in a plane orthogonal to a longitudinal direction of the first insulator. 
     
     
       6. The socket according to  claim 1 , wherein the contacts each include a mounting portion that is bent to project from the support portion. 
     
     
       7. An electronic device, comprising the socket according to  claim 1 .
